Question

find the area of quadrilateral whose diagnol is 5.5cm and two heights is 1.5cm and 2.5cm .​

Answer 1

Answer:

answer will be 11cm

Step-by-step explanation:

because formula for general quadrilateral is 1\2×d×(h1+h2)

=1\2×5.5×(1.5+2.5)

=1\2×5.5×4

=1\2×22

=11cm

Answer 2

Answer:

The above mentioned questions answer is 11 sq.cm

Step-by-step explanation:

Let:-

Length of the diagonal of the quadrilateral be "d"

And,

The two heights of the quadrilateral be respectively "h1" and "h2"

Given:-

Length of diagonal = d = 5.5 cm

and,

1st height = h1 = 1.5 cm

2nd height = h2 = 2.5 cm

Now,

Area of quadrilateral as per formula is

=product of half of the diagonal and sum of their heights

= (d/2)(h1 + h2)

={(5.5 cm /2)(1.5 cm + 2.5 cm)}

= (5.5 cm/2)× 4

= 5.5 cm × 2 cm

= 11 sq.cm
